EDWIN J. NEWTON, 0F DENVER, COLORADO.

PRINTING-PRESS.

To all whom it may concern:

Be it known that I, EDWIN J. NEWTON, a citizen of the United States, residing in the city and county of Denver and State of Colorado, have invented new and useful Improvements in Printing-Presses, of which the following is a specification.

My invention relates to that class of printing machines which are provided with means whereby one portion of a form of type may be made to print a certain color and a different portion of the same form print a different color with one impression.

The object of my invention is to provide a simple and convenient method for attaining the result above stated. To accomplish this result I provide a track for each color desired, said tracks formed of a plurality of similar sections which can be readily adjusted to form either a high or a low track at any predetermined point, and arrange a plurality of type inking rollers, one or more for each color desired, said rollers provided with suitable controlling wheels adapted to run on said tracks as said rollers are moved over the face of the type by the press mechanism.

Although various modifications of my invention might be made, I prefer to use the form illustrated in the accompanying drawings, in which Figure 1 is a plan view of a chase holdin a form of type, said chase being constructed in accordance with the principles involved in my invention. Fig. 2 is a cross section on the line I, I, looking in the direction indicated by the arrows U, U. Fig. 3 is an end elevation of said chase looking in the direction indicated by the arrow Q. Fig. 4: is a side elevation, on a larger scale, of one of the sections forming a track, as will be hereinafter explained. Fig. 5 is an end elevation of the piece shown in side elevation in Fig. 4. Fig. 6 is a side elevation of another section of a track, which is used for raising or lowering the ink rollers, as will be hereinafter explained. Fig. 7 is an end elevation of the piece shown in side elevation in Fig. 6. Fig. 8 is a side elevation of a similar track section used for raising and lowering the ink roller with a short distance of travel, as will be hereinafter explained. Fig. 9 is an end elevation of the piece shown in side elevation in Fig. 8. Fig. 10 is a plan view of the means used for supplying ink to the inking rollers, and a portion of the chase and con- Specification of Letters Patent.

necting tracks. Fig. 11 is an end elevation of the mechanism shown in plan in Fig. 10. Fig. 12 is an end elevation of a modification of this invention as applied to printing presses using a cylindrical form.

Similar letters represent similar parts in all the views.

The chase, A, in which the form of type is -locked in the usual manner, is machined on two of its sides as A A as shown.

A pair of tracks, B, B, for each color required are formed by assembling the sections 15 with as many of the sections B or B as may be required to give the desired operation of the inking rollers.

The assembled track is held secure by the clamping action between the chase, A, and the buckstave, C, produced by the screws or bolts D.

The sections B B and B are formed with shoulders X. Said shoulders are shown resting on strips of metal, E, which hold them from vertical movement. They might as easily be made to rest on the chase A, and on the buckstave C, to save space on two color work.

F, F are spacing blocks.

G and H are the type inking rollers. and H are their respective shafts.

G G are the controlling wheels for the roller G and are mounted on the shaft G H H are the controlling wheels for the roller H and are mounted on the shaft H The controlling wheels G and 11 run on a separate pair of tracks.

Referring to the detail views of the track section B note that the distance from the shoulder X to the face Y is less than the distance from the shoulder X to the face Z. By this means either a high or low track may be formed. J and K are the permanent track sections, which may be a part of the press.

Referring to Figs. 10 and 11, L and M are the ink supply rollers. N and O are the ink fountains, each containing a different color ink. Ink is carried from the fountain roller N to the ink supply roller L, by the transfer roller P, and from the fountain roller 0 to the ink supply roller M, by the transfer roller R. Sand T are wabble rollers acting to distribute the ink on the ink supply rollers L and M. Note that the track K is shown with a hump K which has the effect of raising the type inking roller H clear of the ink supply roller L. This effect might as easily be accomplished by placing the ink supply roller L below the level of the track K. J and K are depressions in the face of the tracks J and K to insure positive contact between the type inking rollers and the ink supply rollers by allowing clearance for the controlling wheels G and H The operation is as follows: Suppose we wish to do two color work. For example, take the form shown in Fig. 1. We wish to print the entire form with black ink eX- cept the one word Red. This one word we wish to print with red ink. 'We would first complete our form and lock it in the chase in the usual manner. We would then assemble track 13, using sections B with the face Y uppermost. trolling wheel G its lower position, bring ing the type inking roller G into contact with the type. At a point in line with the word Red we must raise the roller Gr from contact with the type in order to avoid inking this word with the same color ink that we use for the rest of the form. To accomplish this we will invert a section B so that the face Z is uppermost, thus giving the controlling wheel G its higher position at this point. Each side of said inverted section we will place a section B with its side W against B The distance from the shoulder X to the face Z of the section B is the same as between the corresponding points on B The distance from the shoulder X to the corner formed at Y on the section B is the same as the distance from the shoulder X to the face Y on B This brings the face Z of section B even with the face Z of the inverted section B and the corner Y of B even with the face of the balance of the track, giving an incline each side of the inverted section B The length of the high part of the track thus formed is determined by the size of the type forming the word which we want the roller G to clear. It may be necessary to interpose several inverted sections B between the sections B or it may be necessary to leave out the inverted section B altogether and use two of the sections B with their sides W together, as shown in Fig. 3. If the type forming said word was very small it would be necessary to use a section B which would give a very short jump to the roller G. We next assemble the track 1 using the sections B with the face Z uppermost except at a point in line with the type forming the word Red. At this point we in vert one or more sections, bringing the face Y uppermost. This will give a normally high track with a low portion interposed. At each end of the low portion we will place sections B in such a manner that the corner Y will be even with the low portion and the face Z even with the higher portion of the track, thus forming an incline. The length This will give the con-- of the low portion of the track is, of course, determined by the size of the type forming the word which we want roller H to ink. We now make the assembled tracks secure by tightening the bolts D. The form is now fastened in the press in position for printing. The permanent track sections J and K are so placed as to form a continua tion of the assembled tracks. We will assume the ink fountain N to be filled with black ink and the ink fountain O filled with red ink. Transfer roller P will carry black ink to the ink supply roller L in the usual manner, where it is distributed evenly over the surface of L by the wabble roller S. Likewise, the transfer roller R will carry red ink to the supply roller M, where it will be distributed by the wabble roller T. In Figs. 10 and 11 the ink supply rollers L and M are supposed to be rotated by a mechanism not shown, which causes black ink to be transferred to the type inking roller G,

and red ink to the roller H. We will now assume the rollers G and H to be moved in the direction of the arrow V, by a mechanism not shown. The controlling wheel H will ride over the hump K on the track K, raising the type inking roller H, which is carrying red ink, clear of the ink supply roller L, which is carrying black ink. The controlling wheel H will ride off from track K onto the assembled track 1 and the controlling wheel G from the track J onto the again, after passing over said word, into N contact with the remainder of the type.

When the type inking roller H reaches the position of the word Red it will be lowered into contact with the type forming this word and be raised again after inking said type, from contact with the remainder of the form.

The backward movement of the type inking rollers will be in all respects similar,

leaving the form in readiness for an impression. If we wlsh to print more than two colors from the same form with one impression, we simply add a roller, a palr of tracks and an ink supply mechanism for each additional color desired. In this case the same principle would be followed in the arrangement of the track sections as that already described for two color work.

In the modification shown in Fig. 12 all the essential principles are retained. The.

only difference is that the tracks are constructed in a circle concentric with the cylindrical form and the operation is continuous instead of reciprocating.

It is immaterial to my invention whether the track B is formed of a plurality of sections, as shown, or by other means, the essential being the raising and lowering of the type inking rollers for the purpose specified. It is immaterial also whether the said means is a part of the chase or form or a part of the press itself.

it is immaterial whether the ink supply consists of automatic .ink fountains, as shown, or one of the more simple means often used.

It will be understood that when I refer to a form of type I also include any of the mechani ail equivalents of type, such as electrotypes, stereotypes, etc.

What I claim and desire to secure by Letters Patent is 1. The combination with a printing machine, a plurality of type inking rollers, each of said rollers mounted on a suitable shaft, controlling wheels mounted on said shaft, said controlling wheels resting on suitable tracks, said tracks consisting partially of the pieces B with either the faces Y or Z uppermost, as may be required to form either a high or a low track at any predetermined point, and the pieces B or the pieces B clamped together by the buckstave C substantially as described, and means for supplying ink to said rollers.

2."he combination with a printing machine, a plurality of type inking rollers, each of said rollers mounted on a suitable shaft, controlling wneels mounted on said shaft, said controlling wheels resting on suitable tracks, said tracks consisting partially of assembled pieces clamped together, said pieces formed with shoulders to resist perpendicular pressure, and otherwise proportioned that a high or a low track may be formed at any predetermined point, and means for supplying ink to said rollers.

3. The combination with a printing machine, a plurality of type inking rollers, each of aid rollers mounted on a suitable shaft, controlling Wheels mounted on said shaft, said controlling wheels resting on suitable tracks, said tracks consisting partially of assembled pieces clamped together, said pieces so shaped that each piece is capable of forming a portion of either a high or a low track.
